Find the battery and fuse compartment. Advertisement. Description: Fluke 87V & 233: How To Test Fuses In A Multimeter The new Fluke 87V has improved measurement functions, trouble-shooting features, resolution and accuracy to solve more problems on motor drives, in plant automation, power distribution and electro-mechanical Now you can work in two places at once. Fuse is an electrical safety device which aids in preventing overcurrent. This article will provide you with information on how to test a fuse with a multimeter, regardless of the type of fuse. You should receive a reading of 0. We can check the fuse visually to see if it's broken or we can do an electrical test on the fuse using a multimeter to see if it's good or blown. Learn about testing for a blown fuse. But before going through the trouble and expense of replacing the heating element, you should test the device’s thermal fuse. Also, I have a Duo. At room temperature, testing the thermal fuse should produce a reading of zero. Learn what each of these fuses is and how to test each of these fuses below. This is a safety dev… This is usually found on the back, but is also sometimes on the side of some models. If the meter does not indicate 0, but reads infinity, your thermostat should be replaced. Place each of the meter's probes onto the wire terminals. A functional thermal overload switch will cause the needle to move to "0". The beep, an audible indicator, permits technicians to focus on testing procedures without looking at the multimeter display. Test The Thermal Fuse with a Multimeter or Bypass It. How to Test a Thermocouple with a MultiMeter. Testing a dryer door switch is a simple process. A digital multimeter’s Continuity Test mode can be used to test switches, fuses, electrical connections, conductors and other components. The thermal fuse shuts down the dryer when it starts to overheat. These fuses supply the branch circuits in your home to run lights, outlets, and appliances. If you test the thermocouple with the multimeter and you get a reading above 25, then you have another issue. Leave a comment. Here is the part on how to test a fuse. Step 10 Raise the front of the dryer tub slightly, then slide the belt off. Test: Disconnect all connecting wires and check for continuity across the hi-limit thermostat or sensor set. If you do bypass the fuse, remember to remove the electrical tape bypassing the dryer immediately after the test. Disconnect the wires from the thermal fuse by gently pulling on them. Home breakers are the lifeline of your household electrical needs. Go through your manual in order to verify the location. The meter may have more than one battery and they may be of different sizes. How To Test A Thermal Fuse Without A Multimeter Testing the thermal fuse in your appliance is simple and can usually be done using various methods, all in less than 5 minutes. If the multimeter needle fails to move, this indicates the thermal fuse has blown. Plug fuses screw in and come in 15, 20, and 30-amp ratings. Visual Test of a Fuse. If you get a measurement of 1, that means no electricity can flow and the fuse is blown. In order to test the component, you must first remove it from your dryer. But if a thermal fuse is tested when it is heated to its limit, a reading of infinity should be produced. Use a multimeter to test the thermostat's resistance by setting it to the RX 1 setting. You will read continuity across a good element ( 8-12 ohms is an average element ). The first test is to do a visual check of the fuse. The fuse is self-replaceable. A thermal fuse is there any way to test without a meter - Answered by a verified Appliance Technician We use cookies to give you the best possible experience on our website. Multimeters read both volts and ohms. Next, switch on your multimeter so it’s set to ohms, a continuity measurement. Set the multimeter display to read Rx1, or the lowest setting, and touch a probe to each of the thermal fuse wires. If you are using a multimeter, set the multimeter to the ohm setting.
